SUN_POSTN:       200.69d {+13h 22m 45s}   -8.71d {-08d 42' 20"}
SUN_DIST:         65.87 [deg]   Sun_angle= -4.5 [hr] (East of Sun)
MOON_POSTN:      234.91d {+15h 39m 39s}  -15.11d {-15d 06' 34"}
MOON_DIST:        33.39 [deg]
MOON_ILLUM:      9 [%]
GAL_COORDS:        0.47, -0.94 [deg] galactic lon,lat of the burst (or transient)
ECL_COORDS:      267.89, -5.60 [deg] ecliptic lon,lat of the burst (or transient)
COMMENTS:        SWIFT Figure-of-Merit decision.  
COMMENTS:        This was of sufficient merit to become the new Automated Target;  
COMMENTS:        but if the Current PPT has a greater merit, then we will not request a slew.  
COMMENTS:        This matches a source in the ground catalog: SAX1750.8-2900,   delta=0.040 [deg].  
COMMENTS:           
COMMENTS:        The next comments were copied from the BAT_POS Notice:  
COMMENTS:        This is a rate trigger.  
COMMENTS:        A point_source was found.  
COMMENTS:        This matches a source in the on-board catalog.  
COMMENTS:        This is not a GRB.  
COMMENTS:        Since the IMAGE_SIGNIF is less than 7 sigma, this is a questionable detection.  
COMMENTS:        This trigger occurred at longitude,latitude = 185.93,8.89 [deg].
